Under Pressure Drilling

Under Pressure Drillings

Hot tapping is a term describing the cutting of a hole in an existing pressure main. A tapping sleeve and valve are used to facilitate the cutting of the hole in the main while under pressure, providing a permanent branch connection. This can be performed on all types of pipe and under many flow and pressure conditions without interruption to the system.


At MTS Contracting we can supply a full hot tap service on a range of sizes and pressures.


We can supply and fit the tees whether they are bolted, grouted or welded and supply the valves.
